Sparsity Averaging for Compressive Imaging
Rafael E. Carrillo, Jason D. McEwen, Dimitri Van De Ville +2
We discuss a novel sparsity prior for compressive imaging in the context of the theory of compressed sensing with coherent redundant dictionaries, based on the observation that nat…
Sparse image reconstruction on the sphere: implications of a new sampling theorem
J. D. McEwen, G. Puy, J. -Ph. Thiran +3
We study the impact of sampling theorems on the fidelity of sparse image reconstruction on the sphere. We discuss how a reduction in the number of samples required to represent all…
Sampling theorems and compressive sensing on the sphere
J. D. McEwen, G. Puy, J. -Ph. Thiran +3
We discuss a novel sampling theorem on the sphere developed by McEwen & Wiaux recently through an association between the sphere and the torus. To represent a band-limited signal e…
Implications for compressed sensing of a new sampling theorem on the sphere
J. D. McEwen, G. Puy, J. -Ph. Thiran +3
A sampling theorem on the sphere has been developed recently, requiring half as many samples as alternative equiangular sampling theorems on the sphere. A reduction by a factor of…
